help with extrusion multipiler calibration
hey guys,
I need help with the calibration of the extrusion multipiler ( https://help.prusa3d.com/article/extrusion-multiplier-calibration_2257)
Since this sheet has in some areas a lot of space between the lines, it looks like underextrusion, espacially near the holes. The sheet was printed with "DasFilament" ( https://www.dasfilament.de/filament-spulen/pla-1-75-mm/683/pla-filament-1-75-mm-toms3d-infinity-blue-1-kg?c=11) with extrusion multipiler: 1
After reading https://help.prusa3d.com/article/extrusion-multiplier-calibration_2257 I tried it with the visual method
I tried a few prints, but I'm not sure if it get's worse or better:
extrusion multipiler 1:
extrusion multipiler 1,05:
extrusion multipiler 1,1:
extrusion multipiler 1,2:
with holes:
I'm a bit concerned why the sheet has the space between some lines and the cube not, maybe someone can help me.
Currently I print the cube to test it with the caliper tool.

You might find the @hyiger fork of Prusaslicer with calibration added to be useful. Extrusion multiplier was fairly easy and I ended up with a value close to 1, 1.03 or so. I found the wall and measurement method more useful (deterministic) than the flat plaque method. For the particular filament I'm working with a lot of tests give indeterminate results, as it seems to work well over a wide range of settings. I never see dramatic results like the YouTube videos. Temperature towers and fan towers can be the same, with no obvious choice being better than all others.

I use both methods. The wall method is accurate (contrary to some youtubers) if you turn off variable layer heights and switch the Arachne wall generator to "Classic". I would also suggest using micrometers instead of calipers.

I tried with the Youtube video, but it always fails at "pressure advance calibration" with "gcode cropped of length"
I retry it with the fork from @hyiger, thanks so far!

You can ignore the message "gcode cropped of length" it prints just fine
